Magnons reveal topology and dynamics of a skyrmion crystal
Raphael Ayache, Nilotpal Chakraborty, Manabendra Kuiri +11
Although individual skyrmions are topologically protected objects, their cooperative crystalline order is fragile, easily disrupted by thermal fluctuations or other external pertur…
Non-reciprocal Ising gauge theory
Nilotpal Chakraborty, Anton Souslov, Claudio Castelnovo
Non-reciprocity and geometric frustration enable many-body systems to avoid crystalline order and instead exhibit complex, liquid-like behavior. Here we show that their interplay i…
Fractional diffusion without disorder in two dimensions
Nilotpal Chakraborty, Markus Heyl, Roderich Moessner
We analyse how simple local constraints in two dimensions lead a defect to exhibit robust, non-transient, and tunable, subdiffusion. We uncover a rich dynamical phenomenology reali…
Entanglemons: Cross-platform protected qubits from entanglement
Nilotpal Chakraborty, Roderich Moessner, Benoit Doucot
A crucial ingredient for scalable fault-tolerant quantum computing is the construction of logical qubits with low error rates and intrinsic noise protection. We propose a cross-pla…
Entanglement smectic and stripe order
Nilotpal Chakraborty, Roderich Moessner, Benoit Doucot
Spontaneous symmetry breaking and more recently entanglement are two cornerstones of quantum matter. We introduce the notion of anisotropic entanglement ordered phases, where the s…
Riemann meets Goldstone: magnon scattering off quantum Hall skyrmion crystals probes interplay of symmetry breaking and topology
Nilotpal Chakraborty, Roderich Moessner, Benoit Doucot
We introduce a model to study magnon scattering in skyrmion crystals, sandwiched between ferromagnets which act as the source of magnons. Skyrmions are topological objects while sk…
Spectral response of disorder-free localized lattice gauge theories
Nilotpal Chakraborty, Markus Heyl, Petr Karpov +1
We show that certain lattice gauge theories exhibiting disorder-free localization have a characteristic response in spatially averaged spectral functions: a few sharp peaks combine…
Disorder-free localization transition in a two-dimensional lattice gauge theory
Nilotpal Chakraborty, Markus Heyl, Petr Karpov +1
Disorder-free localization is a novel mechanism for ergodicity breaking which can occur in interacting quantum many-body systems such as lattice gauge theories (LGTs). While the na…
Computational modeling of perfusion in dense solid tumors
Mohammad Mehedi Hasan Akash, Nilotpal Chakraborty, Saikat Basu
Tracking and characterizing the blood uptake process within solid pancreatic tumors and the subsequent spatio-temporal distribution of red blood cells are critical to the clinical…
Domain wall competition in the Chern insulating regime of twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Nilotpal Chakraborty +2
We consider magic-angle twisted bilayer graphene (TBG) at filling , where experiments have observed a robust quantized anomalous Hall effect. This has been attributed to the…
Ramsey interferometry of non-Hermitian quantum impurities
F. Tonielli, N. Chakraborty, F. Grusdt +1
We introduce a Ramsey pulse scheme which extracts the non-Hermitian Hamiltonian associated to an arbitrary Lindblad dynamics. We propose a realted protocol to measure via interfero…
Carrier transport theory for twisted bilayer graphene in the metallic regime
Gargee Sharma, Indra Yudhistira, Nilotpal Chakraborty +4
Understanding the normal-metal state transport in twisted bilayer graphene near magic angle is of fundamental importance as it provides insights into the mechanisms responsible for…
Gauge phonon dominated resistivity in twisted bilayer graphene near magic angle
I. Yudhistira, N. Chakraborty, G. Sharma +5
Recent experiments on twisted bilayer graphene (tBG) close to magic angle show that a small relative rotation in a van der Waals heterostructure greatly alters its electronic prope…
Optical and Infrared Photometry of the Nearby SN 2017cbv
Jerrick Wee, Nilotpal Chakraborty, Jiayun Wang +1
On 2017 March 11, the DLT40 Transient Discovery Survey discovered SN 2017cbv in NGC5643, a Type 2 Seyfert Galaxy in the Lupus Constellation. SN 2017cbv went on to become a bright T…
Microscopic theory for electron hydrodynamics in monolayer and bilayer graphene
Derek Y. H. Ho, Indra Yudhistira, Nilotpal Chakraborty +1
Electrons behave like a classical fluid with a momentum distribution function that varies slowly in space and time when the quantum mechanical carrier-carrier scattering dominates…
